2 Claims.

(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 'The'invention described herein may be manufactured and used by or for the ;3overnment for governmental purposes withou 13h? payment to us of any royality thereon.

The subject of this invention is amount for ;anti- .aircraft guns.

:In anti-aircraft gun mounts mobility, rapidity f vemplacing and stability are characteristics of utmost importance. A consideration of these cardinal requirements when attended by limitation in weight imposes difilculties which have been only partly :met in designs heretofore developed.

The present invention therefore aims to provide a mount embodying all the advantages of both the mobile carriage and semi-fixed platform types and accomplishes this purpose by means of a novel arrangement in which the outriggers constituting the base of the mount when in the firing position are individually folded and then folded in pairs to form the frame of a wheeled vehicle With the foregoing and other objects in view, our invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed with- .out departing from the spirit of the invention.

A practical embodiment of the invention is illustrated in the accompany drawings, wherein:

Fig. 1 is a view in side elevation of the mount in traveling position;

Fig. 2 is a plan view of the mount in firing position;

Fig. 3 is a fragmentary end view partly in elevation and partly in section;

Fig. 4 is a diagrammatic view of the emplaced mount;

Fig. 5 is a sectional plan view of the pedestal;

Fig.6 is a longitudinal sectional view through the pedestal showing one of the platform supports.

Referring to the drawings by numerals of reference:

In carrying out the invention the gun 5 with its attendant structure is mounted on a top carriage 6 which is rotatable on a pedestal 7 whose base 8 forms a spade for engaging the ground. Hinged as at 99 to the pedestal are four arms or outriggers H] which are spaced equi-distantly apart and are each formed in three sections Illa, lllb, lflc, pivotally joined as at H and [2 so as to be capable of being folded, preferably vertically, upon one another.

The Outriggers when individually folded and then folded in pairs as shown in Fig. 1 comprise a vehicle frame which may be supported at each end by the bogie units I3-l3 and may be secured thereto in any manner, specihcally by providing clamping screws Ifi-M on the cross transoms of 5 the bogies.

For the purpose of elevating the mount a sufficient distance to permit withdrawal of the bogie units and for subsequently lowering it to the ground there are provided a pair of jacks l5-l5 10 carried by the base 8 of the pedestal.

The operation of changing from the traveling to the emplaced position may be performed in a short time. The clamps I l-l4 having been released the jacks A5 are brought into play to first l5 elevate the mount suificiently to run out the bogies and then to lower the mount until almost on the ground. The outriggers are then swung to the desired position, which is preferably radial, and the load removed from the jacks. The two outer .20 sections of each outrigger are then unfolded -and laid on the ground asshown in Fig. 2'.

In the diagrammatic view illustrated in Fig. {l the middle third of the base is indicated by the square I6. When the resultant of all forces acting on the mount is kept within the square it'will be a force of compression. The outer circle l'l indicates the points at which the resultant will enter the ground at 0 elevation and the inner circle l8 indicates the points for 15 elevation. Since anti-aircraft firing is seldom conducted at angles below 15 elevation it will be seen that resultant force under normal conditions of use will always be Well within the area of compression.

The working platform l9 which rests-on the Outriggers when the mount is emplaced consists of four units, the inner section 20 of each unit hinged to the outer section 2| and the latter in turn hinged to a support 22 fixed to the pedestal. Toggle members 23 carried by each pair of outriggers provide a support for the inner sections of adjacent units, as shown in Fig. 2. The platform is arranged for the traveling position by folding the inner sections onto the outer sections and then swinging the units to an upright position where they will be spaced by the frames 24 on the supports 22 and confined between the folded Outriggers. The upright frames 2 are each formed with a saddle 25 for the purpose of establishing a gun rest and they are hinged in a manner to permit being lowered.

The seats 26 and fuse setter 21 may be mounted so as to be removed or they may be swung clear, should it become necessary or desirable to alter the normal arrangements of folding the outriggers as an expedient in removing the mount from its emplaced position.

We claim:

1. In a gun mount, a pedestal, a set of individually foldable outriggers hinged equi-distantly about the pedestal, said Outriggers when folded in pairs arranged to constitute the frame of a; vehicle, a mobile unit for supporting each pair of Outriggers, Jacks carried by the pedestal, supports proJectlng Irom the pedestal and a sectional foldable platrorm carried by said supports.

2. In a gun mount, a pedestal, a platform carried thereby, outriggers hinged to the pedestal, and toggle members on said Outriggers for supporting the platform.
